Federation of European Microbiological Societies (FEMS) is an international European scientific organization, formed by the union of a number of national organizations; there are now 53 members from 36 European countries, regular and provisional. Members can apply for fellowships, grants and/or support when organising a meeting. FEMS facilitates exchange of scientific knowledge to all microbiologists in Europe and worldwide by publishing five microbiology journals and organising a biennial congress for microbiologists around the world. It also initiates campaigns such as the European Academy of Microbiology (EAM) and the European Microbiology Forum (EMF).
Since 1977, it is the sponsor of FEMS Microbiology Letters, a single journal, that was later on followed by 4 more journals:
Originally published for the Society by Elsevier, then by Wiley-Blackwell, they are now published by Oxford University Press.
